Abstract
In one example, a processing system including at least one processor may obtain at least one frame of a volumetric video, obtain a first viewport of a client device, render a plurality of two-dimensional subframes comprising two-dimensional projections of the at least one frame of the volumetric video, based upon the first viewport of the client device, and transmit the plurality of two-dimensional subframes to the client device. In another example, a processing system including at least one processor may request a volumetric video from a network-based proxy, provide a viewport to the network-based proxy, obtain a plurality of two-dimensional subframes from the network-based proxy in accordance with the viewport, select at least one of the plurality of two-dimensional subframes to present, and display the at least one two-dimensional subframe that is selected.
